'Bias' in the Bible

They came and said to Him, “Teacher, we know that You are truthful and have no personal bias toward anyone; for You are not influenced by outward appearances or social status, but in truth You teach the way of God. Is it lawful [according to Jewish law and tradition] to pay the poll-tax to [Tiberius] Caesar, or not?

I solemnly charge you in the presence of God and of Christ Jesus and of His chosen angels, to maintain these principles without bias, doing nothing in a spirit of partiality.
